Abstract
This invention provides a RAM data selection circuit in which the screen data from the graphic display RAM and the text display RAM incorporated in the personal computer are simultaneously outputted and a data selection means adapted to output either of the two screen data preferentially by the dot unit to the monitor TV is provided, thereby rapidly enabling the superimposing of graphic and text data on the screen.
